Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Builds a rich fat base in which the vegetables soften and take on colour.
Carrots
Add sweetness and body to the stock as they cook down.
Haddock
Releases flavour and gelatin into the stock during the long simmer, giving depth.
Whiting fillets
Provide tender pieces of delicate fish that cook quickly in the hot stock.

The step that matters

Skimming the stock as it comes to a boil. Skimming removes coagulated proteins and impurities that would otherwise cloud the soup and taste bitter or scummy, leaving a clearer, cleaner broth.

Swap the onion

How well each one fits the dish's main ingredients (butter, carrot, shallot, clove, thyme, parsley, haddock):
